My invention relates to cabs for tractors and has particular reference to a -cab designed for use upon a tractor of the Fordson type, for the purpose of protecting the operator of the cab from inclement weather.

The primary object of my vention is the" provision of a cab for tractors ,hich has a bottom frame-work with provisipns thereon for attachin the frame to a tractor and upon which t e housing from the cab is built, the bottom frame and attaching means to the tractor affordin iexibility and being easily and simply attac ed to the tractor and forming a suiiiciently heavy frame-work whereby the housing forming the cab 1s supported firmly and yet without being so soli y built as to result in the windows in the ab bem broken as is likely to occur when the structure is too rigid.

Another and further object of my invention is the provision' of a cab, the housingl of which is light and simple in constructlon and which forms adequate protection during the cold and wintry weather, and having a plurality of windows therein which .may be opened to provide adequate ventilation and also to render the cab operii to the air and breezes during the summer wi ,I en the weather lS hot. Uf

I am aware that various `-absw M been designed for attachment totraeviimogfwtlns type, but these cabs are eitheniy' r construction and not substanti l enough to afford adequate protection to the operator of the tractor, or they are so heavy that the weight superimposed upon the additional tractor increases the burden and lessens the eiicienc of the tractor; and furthermore, these ca s are exceedingly diiiicult to detach from' the tractor if for any purpose it is desired to remove them for repair purposes or the like. In my improved cab construction a cab is easily attached to the tractor and can be removed therefrom if it is desired for any purpose to tear down the tractor for purposes of repair, andI therefore the construction is simple and easily manufactured and easily attached to e tractor.

These and other objects of m invention will be further and better un erstood by reference to the accompanying sheets of drawings and in which- Fig. 1 is a side elevational view of the tractor having my improved cabs mounted thereon; f

.tofore Fig. 2 is a rear elevational view of the tractor shown with the cab attached; and

Fig. 3 is a front elevational View of the cab removed from' the tractor.

Referring now specifically to the drawings and in which like to like parts throughout, a tractor l10 is shown comprising a frame 11, an engine 12, front wheels 13, a pair of rear wheels 14 and 15 connected by an axle 16 havin a housin 17 surrounding the said axle and connected to a diHerential housing 18. A crank case .19 is provided to which a transmission houslng 20 is secured in the usual manner, the said transmission housing 20 having a flange 21 thereonwhichpcooperates with a second g ange 22 of the @crank case,'. and through which bolts 23 pass g the trans mission housing crank se housin together. All of tl se pav s heretofore described are parts co the Fordson type and ich form of my present invention.\`\\, Referring now to the c composing the same I pr gitudinally extending members 24 and 25 respecti 24 extending underneath the axle housing 17 on the right side of the tractor with a bracket 26 at its rear end, having bolts 27 positioned therethrough by means of which the oor board 24 is secured to the bracket 26, the said bracket 26 being flat at eaclr f its ends and is curved at or near its mihdle, being secured at its inner end to the differa to the parts 'de a pair of lonand left floor ly, the member ential housing 18 by means of the bolts 28 which pass through the diderential housing and hold the various sections thereof together. At the forward end of the member 24 another bracket 29 is provided having bolts 30 passing through the outer end thereof, by means of which the floor board 24 is secured to the Iiange 21 of the transmission housing by means of the bolts 23,vv 3 heredescribed, the said bracket 29 extending mwardly and upwardly and is curved laterally to conform to the transmission housing so that the ioorboard 24 at its forward end is securely fastened to the transmission housing and at its rear end is secured to the differential housing. These parts being standard manufacture and therefore only being necessary to provide the brackets and bolts which are slightly longer than those used in the manufacture of the the bracket 26 by the bolts 28 -tractor to secure. these brackets to the houssion housing from the bracket 26. The ioor board is attached to the'bracketBO by the bolts 31, 31 at its rear end and at its forward end has a bracket similar to the bracket 29 heretofore described by means of which the forward end of this iloor board 25 is secured to the transmission housing at its opposite lside in exactly the same manner as has been heretofore descr'bed with relation to the bracket 29.

Secured to the outer edge of the floor board 24 and in vertical relation therewith is a side member 33 having a half circular recess 34 cut therein which fits around the axle housing 17 and brake drum on/the under side thereof and upon which. the lower edge of a panel 35 forming one slde of the cab housing rests in edge to edge relation therewith, the said panel 35 having a half circular opening 36 which lits over the upper ed of the axle housingl17 and brake drum an is supported upon t e memberT 33. At the opposite side of the cab is a vertical member 37.. secured to the member 25 and which corresponds to the member 33 and upon which a anel 38 forming the lower side of the cab ousing is place in exactly the same position as the panel 35 heretofore described, the floor boards 24 and 25 and the side members' 33 and 37 forming the supporting members for the upper housing forming the cab. A pair of front angle posts 39 and 39 are p aced in each of the oorners'of the cab at the front thereof, the said angle posts at their lower ends resting upon the vertical side members 33 and 37, a vertical post 40 being provided which is secured to the angle iron 39, with a lower front member 41 which is`secured at its side to the angle iron 39 and is secured to the iioor board 24 at its lower end. At the rear corner of the cab is another angle 42 to which is secured a post 43, and the outside panel 35 at its rear end which forms the side of the cab, the said panel 35 being secured at its forward end to the angle 39. Mounted above the panel is a pair of vertically extending spaced posts 45 and 46, between which a window 47 is ositioned with windows 48 and 49 placed tween the posts 46 and the post 40 vrespectively and the posts 45 and 43 respective y, these posts together with the corner angles 39 and 42 sup orting a roof plate 50 at one side of the ca The ogposite side of the cab is built in exactly t e same manner as heretofore described, with a roof late 51 sup rted by a rear angle 52 and t e front ang e 39, a vertically extending strip 53 being secured to the said corner angle 52 upon which a rear door 54 is mounte by means of hinges 55, a similar member 56 being positioned at the opposite side of the cab and secured to the angle 42. A front member 58 is provided which is secured to the angle post 39a and the floor board 2.5, above which a post 57 is positioned which 1s also secured to the angle post 39. A frame 59 is mounted between posts 40 and 57 within which a glass window shield or front closure member 60 is ositioned, the said member 60 being pivota y mounted at the center thereof upon pins 61 and 62 by means of which this window is turned into a horizontal position if desired. A. front strip 63 is provided which extends across the forward side under the roof 64 which is supported by the various vertical members in the manner commento roofs on automobiles or the like. A front member 65 is also provided which is positioned across the forward end of the cab and is secured to the members 41 and 58 at the upper ends thereof.

Attached to the panel 35 on the outer side thereof by means of bolts 66, 66 is a bracket 67 which is bent over the upper edge of the side member 33 and passes downward on the inside thereof and is secured thereto in any aiproved manner. A similar bracket (not s own) 1s provided on the opposite side of the tractor which is attached to the panel 38 and to the member 37 these brackets serving to hold the rear end of the housing in roper position. A bracket 68 is provided which is Vattached to the side member 33 at the front end thereof by means of bolts 70, 70 and is bent over the upper edge of the member 33 and extends upwardly inside of the corner post 39. A similar bracket (not shown) is provided at the op osite side of the housing. It will thus be un erstood that the cab housing can easily be attached to or removed from the side members 33 and 37 by removing the bolts holding the brackets for purposes of repair or the like.

It will thus be understood that a complete housing is provided which extends over the rear end of the tractor and protects the operator thereof at all times, both in winter and summer weather this housing being supported by floor sills .24 and 25 and the brackets secured thereto hold the cab securely in position.

There may be various other modifications of the invention, and it is my intention to cover all such modifications which do not involve a departure from the ,s irit and scope of the invention as set forth 1n the following claims.

I claim:

1. A cab for tractors comprising a pair of longitudinally extending1 ioor members positioned below the axle ousing of the tractor, a pair of brackets'secured to the differential housing and to the rear ends of the said floor members, a pair of brackets secured to the transmission housing and to the forward ends of the said fioor members, and a superstructure mounted upon the said oor l0 members. Y

2. A cab for tractors comprising in co1nbination, a pair of longitudinally extending ioor plates, a plurality of brackets at the forward end of the said Hoor plates whereby the said floor plates are secured to the transmission housing of the tractor, a pair of curved brackets extending outwardly from the diiferential housing, and means for securing the said Hoor plates at their rear ends to the latter named brackets and a su- I0 perstructure carried b said noor plates.
